deadtime, and the no radius-server host global configuration commands. To disable inaccessible authentication
bypass, use the no authentication event server dead action interface configuration command. To disable
critical voice VLAN, use the no authentication event server dead action authorize voice interface
configuration command.

This example shows how to configure the inaccessible authentication bypass feature:
Switch(config)# radius-server dead-criteria time 30 tries 20
Switch(config)# radius-server deadtime 60
Switch(config)# radius-server host 1.1.1.2 acct-port 1550 auth-port 1560 test username user1
idle-time 30 key abc1234
Switch(config)# dot1x critical eapol
Switch(config)# dot1x critical recovery delay 2000
Switch(config)# interface gigabitethernet 1/0/1
Switch(config-if)# dot1x critical
